That's it. I've had enough! I no longer want to deal with [person or thing here] after all I'm no longer even happy trying, so there I'm done and I'm just holding my great grudge now.
Wow, this gets pretty intense right about here, this final moment that I arm myself with this grudge. I will not let myself forget (or think otherwise) that anything could work out; but just stop to think, what if? What if it was just bad timing this time, what if I may have just overreacted? Perhaps things could have gone different and things could be different now, perhaps the other person did us wrong, (probably the best way to look at every situation is to look at the situation for their POV and your POV and try to understand the differences, a simple misunderstanding with a person can absolutely lead to conflict!) We are all humans with emotions that can sometimes get the best of us, we need to "remember what we learned."
You may forgive someone when you understand them, it's an invisible anchor that's suddenly lifted, all that weight for some past [hashed] issue. We all need to understand what causes the tension to begin with. For example I'm [mad] because I heard mom is not going to come over for dinner... Was there a higher cause for this issue [like it was getting too late or maybe it was too stressful for mom due to the upcoming weather forecast?] in a scenario such as this we may take personal offense to this. Simply put there was a [minor decline] It may have been a great night for this dinner but Lets move on and try again to be happy.
Not everyone thinks the way you think, knows the things you know, believes the things you believe, nor acts the way you would act. Remember this and you will go a long way in getting along with people. ---Arthur Forman.
